preparation example Construction

[0023] The preparation method step of above-mentioned high-strength heat insulation board is as follows:

[0024] (1) Put the refractory fiber into the water, add an appropriate amount of sodium fluorosilicate, put the raw material, water and sodium fluorosilicate in the stirring tank, stir for 10-30 minutes and disperse evenly;

[0025] (2) Place the skeleton support material in a metal tray with mesh, put the metal tray into the stirring tank, connect the vacuum pipe, absorb the refractory fiber in the liquid, until the refractory fiber covers the entire support material, stop vacuuming;

[0026] (3) Take the tray out of the mixing tank, turn it over to the wooden tray, put it on the baking rack, push the semi-finished product on the baking rack into the drying room, and dry it at 110-300 ° C for 10-24 hours;

[0027] (4) Plane and trim the dried semi-finished product from the baking rack, paste the processed semi-finished product on the front and back, fiber paper and alumi...

Embodiment 1

[0029] Put the refractory aluminum silicate fiber into the water, the weight ratio of refractory fiber and water is 1:5, then add 1% by weight of sodium fluorosilicate, put the raw material, water and sodium fluorosilicate in the stirring tank, stir Disperse evenly after 20 minutes, place the hexagonal grid stainless steel 304 skeleton support material in a metal tray with mesh, put the metal tray into the stirring tank, connect the vacuum pipeline, and absorb the refractory fiber in the liquid until the refractory fiber is covered Fill the entire support material, stop vacuuming, take the tray out of the mixing tank, turn it over to the wooden tray, place it on the baking rack, push the semi-finished product on the baking rack into the drying room, and dry it at 150°C for 20 hours Plane and trim the dried semi-finished products from the baking rack, paste the processed semi-finished products on the front and back, fiber paper and aluminum film, put them on wooden brackets, pas...

Embodiment 2

[0031] Put the refractory alumina fiber into the water, the weight ratio of refractory fiber and water is 1:8, then add 2% by weight of sodium fluorosilicate, put the raw material, water and sodium fluorosilicate in the stirring tank, stir for 30 Disperse evenly after 1 minute, place the pentagonal grid stainless steel 304 skeleton support material in a metal tray with mesh, put the metal tray into the stirring tank, connect the vacuum pipeline, and absorb the refractory fiber in the liquid until the refractory fiber is covered. Stop vacuuming the entire support material, take the tray out of the mixing tank, turn it over to the wooden tray, place it on the baking rack, push the semi-finished product on the baking rack into the drying room, and dry it at 200 ° C for 15 hours; Plane and trim the dried semi-finished product from the baking rack, paste the processed semi-finished product on the front and back, fiber paper and aluminum film, put it on a wooden bracket, paste it sta...

Abstract

The invention relates to a high-strength thermal-insulation board. The high-strength thermal-insulation board is of a sandwich structure. A middle layer is formed by framework support material and refractory fiber material. Gaps of the framework support material are filled with the refractory fiber material in order to form the structure of the middle layer adopting the framework support material as a framework and having continuous distribution of the refractory fiber material. Two sides of the middle layer are provided with fiber protection layers, outer layers of which are provided with anti-radiation layers. The production method of the high-strength thermal-insulation board has following beneficial effects: the problem that conventional aluminum silicate thermal-insulation material has poor strength and thermal shock resistance at high temperature is solved so that heat efficiency of a cement rotary kiln is improved, energy is saved and manufacturing cost is decreased.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials application, in particular to a high-strength aluminum silicate heat insulation board and a production method thereof. Background technique [0002] With the vigorous development of my country's cement building materials industry, from the previous vertical kiln to the wet kiln to the current dry rotary kiln production line, the technical level of cement production has made great progress. In the current domestic cement dry process production line, rotary The heat insulation problem of the kiln shell has not been effectively solved, resulting in a large amount of heat loss and increasing the production cost. Although there are many types of thermal insulation products at present, there are few thermal insulation materials that meet the requirements of the cement production process. This is due to the large span of the rotary kiln of the cement dry process production line, which...
